2) Id 200 send out from DSC for 4cyl CC without LDM.
3) By stopping Id 193 out and replaced with Id 200 from LDM tested. No good. Cruise Control failure immediately start the engine. Seem like current coding require Id 193 to stay active in PT-Can bus in order for ACC to be functional.
4) Tested getting Id list sent out from DSC, surprising Id 0AA also not there.
The Id list from DSC are :
0B6, 0C4, 0CE, 0E1, 194, 1A0, 1A6, 1D6, 2A6, 4A9 & 5A9
5) It is clear now Id 0AA is CC control status from DME after received Id 193 or 200.
6) From can-bus log data shows CruisePedal signal still Inactive in Id 0AA even received CruiseActive Id 193 command. I suspect is a program bug in 4cyl DME or is not included in 4cyl DME program. I am going to figure out with more testing.

Sorry !! Correction !!
Can Id 0x200 is sent from DME and not DSC in normal Cruise Control VO$540. It disappeared on PT-Can after coded to VO$544 or &541.
I am compiling a list of BMW Can Id from my sniffing results and

to be shared later for those who interested in BMW Can Bus reverse engineering.
Perhaps ACC Stop + Go may be possible in E9x.

The stop go function in later models uses ultrasonic as well as radar to determine distance.
To have it work on an e90 would be awesome
